Warm water Underfloor heating has been around for over 2000 years, the concept behind Underfloor heating is very simple, using a much larger floor area the Underfloor heating pipes generate a much more evenly spread heat source, meaning the system can run at a lower temperature saving you costs on your fuel bills, Underfloor heating acts like a big evenly spread out radiator gently heating the room from the ground up, this requires approximately 20% less energy to achieve the same level of comfort experienced by a traditional radiator.

There are many different advantages to using warm water Underfloor heating, the main one is the energy saved by heating a larger floor space at a lower temperature, other advantages include, more freedom of design from the developers point as radiators take up valuable wall space, also the convection style heating from a radiator systems means the warmest part of the room is the ceiling void, this obviously being a waste of heating and energy. As the warm water underfloor heating radiates slowly through the floor it gives off a much more even heat.

Warm water is circulated from the boiler to the electrically switched zone valves this is for all radiators and underfloor heating. When the room stat calls for heat the water then passes through the zone valves and then into the manifold where the water is circulated through continuous lengths of plastic pipe incased in the floor, which is run at a lower temperature (typically 50°C) whereas radiators are (70°C).
The Extension kits are designed to provide a solution for underfloor heating to single zone extensions + conservatories with a proposed concrete or sand and cement screed floor area up to 40m2, the manifold setup provides excellent water temperature control, blending the hot water from your heating system down to the safe temperatures used in warm water underfloor heating systems.
Our kits include the electrical controls and valves that enable your warm water underfloor system to operate independently from your existing heating system, in line with current building regulation part L.
Perfect for use with a renewable heat source, a carefully designed underfloor heating system offers high efficiency, and maximum cosiness from the ground up.
Hot water delivered to the underfloor heating manifold from the heat source is blended until the correct temperature is reached. In most boiler-fed systems this will be between 40˚C and 55˚C but in a heat pump system can be as low as 30˚C, increasing the efficiency of the heat pump. Ramki will always take into account the heat source when designing a system and specify the flow temperature needed for each room to maintain comfort levels.
